MACHINE FOR TENDERING BEEFSTEAK.

Application filed April 21, 1924. Serial No. 707,898.

To all whom it may concern:

Be it known that I, SIMON P. MICKEY, a citizen of the United States of America, and resident of Gering, Scotts Bluff County, Nebraska, have invented a new and useful Machine for Tendering Beefsteak, of which the following is a specification.

An object of this invention is to provide improved means for tendering beefsteak.

A further object of this invention is to provide an improved construction for a machine for tendering beefsteak.

A further object of this invention is to provide improved means for adjusting a machine to steaks of varying thicknesses.

A further object of this invention is to provide improved means for removing parts of the machine for cleaning.

My invention consists in the construction, arrangement and combination of elements hereinafter set forth, pointed out in the claims and illustrated by the accompanying drawing, inwhich Figure 1 is a perspective of my machine assembled as required for practical use. Fi re 2 is a vertical section of the machine through the bearings and rollers longitudinally. Figure 3 is a vertical section of the machine at right angles to Figure 2. Figure 4 is a cross-section of the shafts at one end of the rollers.

In the construction of the machine as shown the numeral 10 designates a frame preferably formed of metal by molding and provided with and including an integral bracket or hook 11, the entire frame being suitably reenforced by ribs 12, 13 to give it required strength and stability. A screw seat 7 is formed inthe lower portion of the bracket or hook 11 substantially in alinement with the body of the frame 10 and a clamping screw 14 is threaded therein. The screw 14 is provided with a handle 15 mounted loosely in and transversely of its lower end portion and also is formed with a head 16'on its upper end portion. The frame is adapted to be mounted on a shelf or table, one margin of said table'being received in the openmg of the bracket 11, thescrevv 14 being manually adjusted in its seat to causethe head 16 to engage the lower face of the table and clamp the bracket and frame thereto in upright position. A cylindrical boss 17 is formed on the lower portion of the frame 10 and extends laterally therefrom above the bracket 11 and a bearing is formed in said portion of the frame and in said boss. A shaft 18 is journaled in the bearing in the frame and boss 17 and a cap 19 is mounted on one end of shaft adjacent said boss and 1s detachably secured thereto by a pin 20. The cap 19 is formed with a diametrical hole spaced from the end of the shaft and a crank arm 21 is mounted for longitudinal adjustment in said hole and is secured at an adjusted position therein by a set screw 22 threaded in the cap. A pin 23 is mounted through and projects at both ends from the shaft 18 adjacent the end of the bearing opposite to the cap 19 and a toothed roller'24, substantiallycylindrical in form, is mounted loosely on said shaft and is formed with transverse notches adapted to receive end portions of the pin 23 in the end thereof adjacent said bearing (Fig. 4). The frame 10 is forked above the horizontal'plane of the boss 17 and the arms thereof are parallel on their adjacent faces. A hearing block the frame and is formed with edge flanges 26 embracing the sides of said arms to guide and retain the-block in proper relation to the arms. A cylindrical boss 27 is formed onand extends laterally from the block 25 above and substantially parallel with the boss 17 and a bearing is formed in said block and boss 27. A shaft 28 is journaled in the bearing formed in the block 25 and boss 27 and a collar 29 is mounted on said shaft adjacent the boss and is secured thereto by a pin 30. A pin 31 is mounted through and projects at both ends from the shaft 28 adj acent the side of the block 25 opposite the boss 27 and a toothed roller 32, substantially cylindrical in form, is mounted loosely on said shaft and is formed with transverse notches adapted to receive end portions of the pin 31 in the end thereof adjacent said block (Fig 4). The toothedrollers 24 and 32 are shown slightly spaced apart, one above the other. A cap 33 is mounted on the upper ends of the arms of the frame 10 and .25 is slidingly mounted between the arms of is secured thereto by screws 34, and an adthreaded through the cars 37 p and engage the upper faces of the ears 36. The inclination of the shaft 28 relative to the shaft 18 may be varied to separate or bring together the toothed rollers 24 and 32, by manual op eration' of the adjusting screws 38, 39.

In practical use, the degree of separation or interengagement of the rollers 2-1 and 32 is adjusted, the leverage of the crank arm 21 is adjusted and a beef-steak to be treated is introduced between said rollers, the lowermost roller being manually rotated through the shaft 18 and pin 23. Engagement of the steak will rotate the uppermost roller. The steak is mangled, crushed, broken or compressed by passing thru the rollers to any desired extent, dependent on the adjustment of separation of the rollers and thickness ofthe steak.

Either roller 24: or 32 may be removed manually for cleaning, repair or substitution, by outward longitudinal movement on its shaft to release the pin 23 or 31 from 1 the end notches, and can be replaced by an opposite movement. The shafts may be removed from their bearings by withdrawing the pins 23 and 31.

I claim as my invention 1. A. machine for tendering beef steak, comprising a single frame member, means for securing said frame member to a support, shafts mounted substantially parallel in and extending on opposite sides of said,

frame member, one of said shafts being adjustable relative to the other, and toothed rollers removably and replaceably mounted on said shafts, said rollers being wholly at one side of said frame member.

2. A machine for tendering beef steak, comprising a single frame member formed with an integral bracket adapted to embrace a support, .a screw in said bracket adapted to engage said support, a shaft journaled in said frame member, a crank handle on said shaft, a bearing block slidingly mounted in said frame member, a shaft journaled in said block and mating toothed rollers removably and replaceably mounted on said shafts, wholly at one side of said frame member.

3; A machine for tendering beef steak,'

comprising a single frame member, a crankoperated shaft journaled in sald frame member, the frame member being forked above said shaft. a bearing block slidingly mounted in the fork of the frame member.

a shaft mounted for rotation in said block, and mating toothed rollers removably and replaceably mounted on said shafts, wholly at one side of said frame member.

. In a machine for tenderin beef steak,

:1 frame formed with a lateral y-extending boss, 0. crank-operated shaft journaled in rollers removably and replaceably mounted on said shafts.

5. In a machine for tendering beef-steak,

a single frame member, a shaft journaled therein and extending at one end therefrom; a pin mounted in and projecting radially from said shaft adjacent said frame mem-.

her, and a toothed roller formed with an end notch, said roller being removably and replaceably mounted on the extending end of said shaft, the notch therein opening toward said frame member, said pin engaging in said notch. 4

6. In a machine for tendering beef steak, a frame formed with a laterally-extending boss, a shaft journaled in said frame and boss, a bearing block adjustably mounted in said frame and also formed with a boss substantially parallel with the first boss, said bosses being formed with opposing pairs of ears arranged tangentially thereon, adjusting screws threaded in one pair of and engaging the other. ears, and a shaft journaled in said bearing block and its boss.

7. In a meat tendering machine, a single frame member, shafts mounted substantially parallel with each other in and extending on opposite sides of said frame, one of said shafts being adjustable relative to the other, means for rotating one of said shafts, and rollers removably and re laceably mounted on said shafts on the en thereof opposite ,to the rotating means, said rollers being toothed.

8. In a meat tendering machine, a single forked frame member, formed with-a bearing and a, boss thereon, .a bearing block adjustably mounted in said frame member above the bearing and formed with a boss adjacent the first boss, means for adjusting the second boss relative to the first boss, shafts journaled in said bearing and block and in the bosses thereof, said shafts extending from the frame member opposite to the bosses, and toothed rollers removably and replaceably mounted on the extending portions of the shafts wholly on the opposite side of the frame member from said bosses.
